The Geometry of the Drinfeld Curve
- 1.3k Downloads
The purpose of this chapter is to assemble the geometric properties of Y and of the action of G×(μ q+1⋊〈F〉mon) which allows us to calculate its ℓ-adic cohomology (as a module for the monoid G×(μ q+1⋊〈F〉mon)). A large part of this chapter is dedicated to the construction of quotients of Y by the actions of the finite groups G, U and μ q+1.
